Hey everyone, this is my first grow, so a complete novice. I’m using Biodesiel nutrients, and all was going well, till I took the cap off the Biodesiel Green, Part A, and noticed a heap of white floating things on the surface. I’m assuming its mold, but not really sure. I’m about 2 months in, and its a 20 liter container, so didn’t want to throw it out if i could avoid it. Also unsure if i should keep using it for this grow or not. Any and all help is greatly appreciated.
